Answer:
0.1707 N
Explanation:
From the question,
Applying Coulombs law
F = kqq'/r²................... Equation 1
Where F = Electric Force, q = First charge, q' = second charge, r = distance between the charges, k = coulomb's constant
Given: q = -6.67×10⁻⁶ C, q' = -5.27×10⁻⁸C, r = 0.43 m
Constant: k = 8.98×10⁹ Nm²/C²
Substitute these values into equation 1
F = [(-6.67×10⁻⁶)(-5.27×10⁻⁸)(8.98×10⁹)]/(0.43)²
F = (315.655×10⁻⁵)/(0.1849)
F = 1707.17×10⁻⁵
F = 1.7072×10⁻²
F = 0.1707 N
